7.13 Calibrate Compass
(GPS MAP → MAIN MENU → Settings →
Calibrate Compass)
Ideally you should calibrate your compass
before every trip to get the most accurate
bearings.
When the ‘Calibration Required’ prompt is
displayed at the bottom of the COMPASS
screen, go to the Settings menu and select
Calibrate Compass. Follow the on-screen
instructions. Press Cancel to return to the
SETTINGS MENU.
Note: This screen may also be accessed from
the COMPASS screen (section 6.02).
1) Hold GPS level
2) Press Start
3) Turn device around in TWO full circles (720
degrees)
4) Press Stop when completed turning or
Cancel to quit.
An on-screen message ‘Keep turning’ is
replaced with ‘Completed. Press Stop’.
Note: When in motion it is better to use the
GPS compass over the electronic compass.
The GPS compass requires forward motion
to provide a heading; it will not work when
static. See GPS Settings (section 7.09) to
control when the GPS compass overrides the
electronic compass at a preset speed: 'GPS
Used as Heading at'.
Calibrating on a bike
The electronic compass is affected when
brought into proximity with metal objects.
This means that once the GPS unit has been
mounted onto the handlebars of a bike, it
should be re-calibrated.
To do this follow the instructions exactly as
you would if the unit were in your hands.
When asked to turn the compass in two full
circles (720°), you should pick up the bike
with the unit and rotate it as indicated.
When subsequently removed and used for
walking, a further recalibration is required.
It should also be re-calibrated when a
different battery type is inserted, due to the
varying metal content from one battery type
to the next.
